Vapor and liquid flow concurrently through a vertical vessel. A horizontal flow obstructing mixing device is located within the vessel and forces the vapor and liquid to pass in a vertical direction through one or more inlet openings to the mixing device. The mixing device consists of circular top and bottom walls and a cylindrical side wall. Inside the mixing device curved flow baffles are provided. These flow baffles form one or more tangential inlet orifices, which are located as far from the vessel centerline as possible. The entire process stream flows through the one or more tangential inlet orifices at high flow velocity and in a tangential direction into a swirl box. The high momentum of the process stream in the tangential inlet orifices, the pure tangential direction of the stream, and the large distance between the tangential inlet orifice(s) and the vessel centerline result in a violet swirling flow and in a large number of fluid rotations in the swirl box. The large number of fluid rotations in the swirl box is essential to properly mix the stream(s) entering through the tangential inlet orifice(s) with each other. The fluids exit the mixing device in a vertical direction through an outlet opening in the bottom wall of the mixing device. An impingement plate is located below this outlet opening to spread the liquid and to break down the velocity of the jet. The temperature and chemical composition of the outlet stream is equilibrated. |
